sMPRovEMErfIT IN MACHINES FOR lvHLKlNey cows.

Specification'forniing part of Letters Patent No. 25,019, dated August 9, i859.

To pz/ZZ whom it may concern.-

Be it' known that I, JOHN W. KINGMAN, of Dover, in the county of Strafford and State of New Hampshire, have invented a new and useful 4 Machine or Apparatus for Milking Cows and other Ainimals; and I do hereby declare that the same is described andrepresented in the `following specification and drawings, in which- Figure lis a perspective view ofthe apparatus, and Fig. 2 a section'of one of the tubes appliedto the teat of a cow.

i The nature of myy invention or apparatus ivfor milking cows orother animals consists in partially covering the upper ends of the teat eupsor tubes with an elastic auge, which w-.ill yield Afor the insertion of the teat, and Aafter itisinserted will contract and grip the ^'feat so as to hold the cup upon it during the 4jprocesspf milking, and at the same time form a packing from the edge of the cup to the .'teat and around it, which will be pressed against the teat by the air outside when the air is exhausted from the inside in the-process of' drawing the milk-from the teat; also, in connecting said feat-cups by means of .fiexible tubes to a vessel provided with an air-pump so arranged as -to draw the air from said vessel and exhaust it,- so as to draw the "milk from the teat-s of the cow or other animal to which the teat-eups are applied.

To enable others skilledv in the art to make V`and use my invention, I will proceed to describe its, construction and the mode of using "it'referring to the accompanying drawings, .in which the Vsame letters of reference indicate like parts in each of the drawings `or figures. v

A is a teat cup or tube, which may be made in the form shown in the drawings or in such other forni as will answer the purpose.' I have made these cups of sheet-tin, but they may be made of some other substances and -answer a good purpose. These cups should be made large enough to slip onto the teats of the animal to be inilked freely andY large enough to reach nearly or quite to where the ,teat joins the bag or udder. 'lhe tops of these cups are provided'with an india-rubber flange B, extending inward an0\upward, so aste receive the teat and grip or clasp it so firmly as to hold the cup onto the teat during vthe process of milking. As the cup hangs down on the india-rubber flange, the inner edge of the flange is higher than the top of the cup, and as the cup is exhausted in drawing the milkthe air on the outside of the flange presses the flange against the teat, and

at the 'same time the rubber contracts from its own elasticity and so maintains a joint lnearly air-tight, or if the teats are wet with rubber made to project above the cup, as

shown at B, Fig. 2. The lower part of the cup A is made conical, terminating in a tapering tube, to which the flexible tube C is appliedfand fastened to connect the -cup A to the pail D, which is to receive the milk, the lower end of the flexible tube being fastened to one of the small tubes E E, which project frolnthe side of the'pail for that purpose.

The pail D may be vmade of sheet-tin or other material and provided with four tubes E E near thel top, to which the fiexible tubes C, before mentioned, are fastened. It isalso provided with brackets G G to hold the top I-I on, which top is provided with a score on the under side filled with india-rubber, so as to make a tight joint by applying the top ,to the pail and turning it so as to carry the hooks I 'I under the brackets G G, which are made inclined, so as to draw the top down tight as it is turned. The under side of the top is made convex land hasa hole in the center with a Valve on the top to close it.

K is a flexible diaphragm, having its edges firmly fastened to the top and its center fastened to the disk L and rod M, which is bored at its lower end and provided with a Valve at N, so that when it is worked by the lever() it works the diaphragm lf. and pumps the airy out ofthe pail and flexible tubes and draws the milk from the animal to which it is applied. 'lhe lever() works on a pin in the bail I?, fastened to the top II, the ends of which bail form4 the hooks L L. 'lhe bail P is perforated, so that the rod Ml works through it, as shown in the drawings.

Having described my invent-ion, I claim" l, rlhc teat cups'or tubes partially covered at their upper ends with an elastic flange,

substantially as described,ywhieh Will yield 2 v I 95,019 'I l v for 'the insertion of the teat and grip it', so as l' and connected with said cup or cups by flexitohold the cup upon the beat during `the pi'oble tubes, so airanged as to exhaust the air cess of milking, and form a. packing between and draw the' milk from the cow or other anithe edge-of the eup and the tea't, which will mai, substantially in the manner described.

be pressed against the teab by the'external 'JOHN 'KINGMAN l S air when the internal air is exhausted. Witnesses: 1
